Which one of the following crop plants is very efficent converter of solar energy, with less water and high temperature?
1 Sorghum and maize
2 Rice and maize
3 Wheat and potato
4 Bajra and barley
Explanation:
\({C_4}\) plants are best in the conversion of solar energy in the presence of less water and high temperature. Examples are Maize and Sorghum.

In \(\mathrm{C}_{4}\) pathway, the \(\mathrm{CO}_{2}\) fixation in mesophyll cells is carried out by the enzyme:
1 Rubisco
2 PEP carboxylase
3 Pyruvate decarboxylase
4 Pyruvate dehydrogenase
Explanation:
In \(\mathrm{C}_{4}\) plants, the carbon dioxide that enters the mesophyll cells is accepted by a 3 -carbon molecule called phospho enol pyruvate (PEP). The enzyme phosphoenol pyruvate carboxylase (PEPcase) catalyses the carboxylation of PEP. \(\mathrm{PEP}+\mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \xrightarrow{\text { PEP carboxylase }} \mathrm{OAA}+\mathrm{P}_{\mathrm{i}}\)

Photosynthetic rate is high in \({C_4}\) plants because
1 No photorespiration
2 Kranz anatomy
3 Photosynthesize in low light intensity
4 None of these
Explanation:
\({C_4}\) plants lack photorespiration, that is why productivity and yields are better in these plants. In addition these plants show tolerance to higher temperatures.

Bundle sheath cells of \({C_4}\) plants show _
1 Thick walled cells and intercellular spaces
2 Thin walled cells and granal chloroplasts
3 Thick walled cells and no intercellular spaces
4 Thin walled cells and no intercellular spaces
Explanation:
Bundle sheath cells pf \({C_4}\) plants show thick walls impervious to gaseous exchange and no intercellular spaces.
